IMPROVEMENT IN CONNECTIONS FOR WROUGHT-IRON BEAMS AND COLUMNS.

Specification forming part of Letters Patent No. 140,455, dated July 1,1873 application filed April 26, 1872.

To all whomt't may concern:

Be it known that I, ADOLPHUS BONZANO, of Phoenixville,Pennsylvania, haveinvented an Improvement in Wrought-Iron Structures, of which thefollowing is a specification:

My invention relates to a mode (too fully described hereafter to needpreliminary descript-ion) of connecting together wrought-iron beams andcolumns, my invention being applicable to bridges, viaducts, warehouses,and other structures of which columns and girders or beams form a part.

Figure 1 is a sectional plan of a wroughtiron beam and columnconstructed and arranged in accordance with my invention; Fig. 2, asectional elevation on the line 1 2 of Fig. 1, looking in the directionof the arrow 1; Fig. 3, a side view of part of the device shown in Fig.1, looking in the direction of the arrow 2 Fig. 4, a modification ofpart of the device shown in Fig. 1; Figs. 5 and 6, views showing amodification of my invention.

In Figs. 1, 2, 3, and 4 the column is made of flanged bars a, similar tothose described in the patent granted to S. J. REEVES on the 17th ofJune, 1862, the said flanged bars being arranged a short distance apartfrom each other for the admission between them of bars 12, according toone modification illustrated and described in the aforesaid patent.These bars I) extend from end to end of the column, excepting wherebeams have to be connected to the latter, and where the beams occur thebars b are discontinued at opposite sides of the column for theadmission of a plate, B, which is riveted or bolted to the flanges ofthe bars composing the column, and forms an integral part of the latter.This plate B projects beyond the flanges of the column on each side ofthe latter, one plate meeting and coinciding with the web of a beam, D,and the other coinciding with the web of the opposite beam D, thesebeams being, in the present instance, of the well-known Phoenix pattern.Each end of the plate B is connected to the adjoining beam bysplicing-plates d and d, which fit snugly against and are riveted orbolted directly to the web of the beam and to the plate B.

It will be noticed that the plate B is deeper than the beam to which itis connected. This arrangement may be adopted when the plate iscomparatively thin ,-as thin, for instance, as the web of the beam-sothat whatever strength may be lost in the plate by making it so thin maybe compensated for by its depth. A plate, B, however, thicker than theweb of the beam, and of the same depth as the said web, may be passedthrough and secured to the column, in which case the splicing-plates maybe bent to fit both the plate B and the web of the column, as shown inFig. 4.

In Fig. 5 two splicing-bars, B and B, pass through the column, and arefitted and riveted or bolted to the webs of the beams D and D, the saidsplicing-bars resting on fillingpieces m arranged at intervals betweenthe flanges of the column-bars, and the splicingbars may be bolted orriveted to the flanges of the column-bars, in which case, however,filling-pieces It should be introduced between the said splicing-barswhere the flanges occur, as shown in Fig. 5.

In constructing the column, Figs. 5 and 6, I prefer to use solid filling-pieces m m arranged at frequent intervals, each piece being longenough to receive two bolts or rivets, by which they are secured to theflanges of the columnbars. (See Fig. 6.)

My invention may also be carried out in connection with the column forwhich Letters Patent were issued September 24, 1872, No. 131,502, to T.0. CLARKE, assignor to CLAR E, REEVES & 00., the said column consistingof flanged bars similar to those described in the aforesaid patent ofREEVES, but some of those bars being arranged in short lengths atintervals so as to present a row of openings, through any of which thesplicing-bars may be passed;

in fact, my invention may be adopted in connection with any wrought-ironcolumn having openings through which the splicing-plates can be passed.

It-will be evident that wrought-iron beams and columns may be connectedtogether economically, both as regards material and workmanship,according to my invention, which may be adopted with advantage in thecon- In testimony \vhereofl have signedinyna-me struction ofbridges,vi2tducts, Warehouses, and to this specification 1n the presenceof two subother structures of which columns or posts scribing witnesses.

and girders form a part. AD OLPI-I 'S BONZANO.

I claim as my invention- Vitnesses: The combination described ofWrought-iron P. G. CAREY,

columns, beams, and splicing-burs. JOHN GRIFFIN.
